To all whom 'it may concern:

Be it known that I, ATwnLL A. PARKER, a citizen oi the United States,residing at VVaterord, in the county of Saratoga and State of New York,have invented certain new and useful Improvements in Pumps, of which thefollowing is a specification.

This invention relates to improvements in double acting pumps, of thetype using diaphragms as the medium for creating the suction andpressure. In my experience I have found that with pumps of this type,considerable difficulty exists, in that by the location of the parts,the sediment in the water prevented the proper seatingy of the valves,hence the apparatus failed to perform the work required of it.

Another disadvantage of the prior con structions known to me, resides inthe fact that the diaphragms have not been so con structed and arrangedas to be positively operated together', to obtain the full stroke andthereby take in and eXpel the full volume of water at each reciprocationof the parts.

According to my present invention, I provide means for overcoming theabove noted difficulties, in that I arrange the inlet and outlet valvesat an angle, to shed the sediment, and couple the diaphragms tohorizontally reciprocating cross heads, causing them to be positivelyand simultaneously moved in a definite path, and at the same time insure the exact reciprocal movement of the diaphragms.

Therefore the object of my invention, is to provide specific details ofconstruction, arranged whereby the desired result is obtained all ofwhich will be hereinafter fully described and particularly pointed outin the claims.

In the drawings Figure l is an end view ofmy improved pump. Fig. 2 is alongitudinal section of the same on the line w-m Fig. 4, the centralvertical partition being broken away to illustrate the diaphragm on theopposite end of the casing. Fig. 3 is a rear elevation of the same. Fig.4C is a front elevation, the upper part of the casing being broken awayto illustrate the outlet valves. Fig. 5 is a plan view. Fig. 6 is ahorizontal section approximately on the line cj-y- Fi 2.

rIhe same numerals refer to like parts in all the figures.

l indicates a casing, provided with two transversely arranged inclinedpartitions 2 and 3, and a central vertical partition 4, disposed betweenthe two partitions 2 and 3. The inclined transverse partitions areprovided each with two openings 5 5 and 6-6, disposed each side theplane of the central vertical partition 4L. Each inlet opening 6 isprovided with an inwardly opening weighted flap valve 7, and the outletopenings 5,l are likewise provided with similar valves 8, opening' inthe same direction. The partition 3, and the lower part of the casing,forms an inlet chamber 9, formed with an opening with which communicatesan inlet pipe l0. An outlet chamber 1l, is formed by the partition 2,and the upper part of the casing, and it is provided with an out-letopening, with which communicates an exit pipe l2. Access may be had tothe chamber ll, by means of a removable cap 13, covering an opening 14in the top of the casing. The vert-ical partition 4; forms in the casingtwo receiving chambers l5 and v16, accessible through an opening 17,covered by a cap 18. rllhe openings 14 and 17, permit of the attendantgetting to the valves 7 and S, with little or no inconvenience.

The oppositie ends of the casing l, are formed with openings 9.0,through which operate the diaphragms 2l and 22. Each diaphragm isclamped to the casing by a ring 2B, secured in place by fastenings, suchas bolts or the like indicated at 24. The diaphragms are of the usualtype, and are of such proportions as will give the desired suction toforce the water in or out the various chambers. To each diaphragm isconnected a cross head 26, having a centrally disposed plate 27, whichfits against the outer face of the diaphragm, and on the inside of thelatter is a plate 28, to which is bolted a plate 27, to fasten the crosshead to the diaphragm. The outer ends of the cross head are formed withopenings 29, and at about the center are ears 30, with a connecting pin31. On the front and rear of the casing are ears 32, provided withopenings 33, forming bearings for a pair of connecting rods 34, theopposite ends of the latter, passing through the openings 29, in thecross heads and secured thereto by nuts.

In operation, any suitable power is applied to the connecting pin 31 andthe cross heads 26 through the connecting rods 34 simultaneouslyreciprocated, hence the diaphragms are likewise reciprocated.

Assuming the cross heads are about at the limit of their movement towardthe right hand side of the casing, as shown in the drawings, and thevalve 7 in receiving chamber 16 is closed, valve 7 in receiving` chamberl5 is open, valve 8 on the left hand end of chamber 11, is open andvalve 8, on the right hand end of said chamber is closed. Immediatelyhowever, the cross head commences to reverse, or move toward the left,the operation and position of the valves will change. Assuming now thecross heads are moving toward the left in direction of the arrow a Fig.6 the pressure created by the diaphragm 22, will close the inlet valve 7in the receiving chamber 16, and thereby sluit off the water in chamber9, and will open the right hand valve S, and force the water inreceiving chamber 15 into the outlet chamber 11, from whence it passesthrough pipe 12. Simultaneously with this action, diaphragm 21, inmoving in direction of the arrow creates a suction in receiving chamber15 wh ich opens valve Ttherein, and draws the water into said chamberfrom chamber 9, the suction however closes the left hand valve8,in=ehamber 11, and thereby the water now being sucked Vfrom chamber 9is contained in receiving chamber 15. As the reciprocating motion of thetwo cross heads is continued, the water from chamber 9, is alternatelydrawn, first into receiving chamber 1G and then into receiving chamber15 from whence it is alternately forced outwardly through the openings 5to chamber 11, thus producing a continuous supply.

By constructing the parts as described, the mud, sand, gravel and othersediment usually present in water, cannot accumulate on the valve seats,as in each instance the latter are arranged at an incline so that ifsuch sediment does not fall of its own weight it will be washed away bythe passage of the water. The heavier particles of the sediment will becaught in the bottoms of the various chambers from which points it canbe quickly and conveniently removed. By arranging the valves to shed thesediment,

-liability of choking the pump is obviated,

hence delays in operation are to a considerable extent reduced to aminimum.

Another advantage of the construction described, is in the fact thediaphragme are vertically disposed, thereby avoiding the cutting andwear of the sand, grit, etc., in the water lodging on them. Furthermoreby mounting the diaphragms in the sides of the casing as set forth, itenables me to operate them in a horizontal direction which is a greatconvenience from a practical and economical standpoint.

The invention is extremely simple in construction, and by reason of thefew parts it is not liable to become out or order. The double actingeffect of the diaphragm gives a constant supply.

Claims 1. In a double acting pump, the combination of a casing havingtwo inclined partitions extendin entirely across and connecting with theside walls of the casing and a centrally vertically disposed partitionwithin the casing and connecting with the interior walls thereof andalso connected with the two inclined partitions to provide two oppositereceiving chambers, there being openings formed in the two inclinedpartitions to afford communication between the receiving chambers andinletand outlet chambers formed by said inclined partitions and thecorners of the casing adjacent thereto, a valve over each of theopenings in the inclined partition to control the inlet and outlet ofthe water, a supply pipe communicating with the inlet chamber in thelower corner of the casing an outlet pipe communicating with the outletchamber in the upper corner of the casing there being alined diaphragmopenings in the side walls of the casing opposite the verticalpartition, a diaphragm in eachl said diaphragm opening, a cross head oneach diaphragm and means for connecting the cross heads to cause them tobe simultaneously operated.

2. In a double acting pump, the combination with a casing formed withinlet and outlet openings, and alined diaphragm openings, the latteropenings being in the side walls of the casing, two inclined partitions,one of said partitions extending across the. casing below the uppercorner thereof, the other said partition extending aeross the easingabove the lower opposite corner thereof, forming with the walls of thecasing, inlet and outlet chambers, a central vertical partition in thecasing extending between and connected to the inclined partitions andforming with the latter receiving chambers, there being openings formedin the inclined partitions for affording communication between thereceiving and inlet and outlet chambers, valves on the upper inclinedsurfaces of the partit-ions for controlling said openings, a diaphragmin each diaphragm opening, a cross head connected to each diaphragm anda pair of connecting rods connected at or near the ends of the crossheads at points beyond the ends of the casing to cause the diaphragms tooperate simultaneously.

In testimony whereof I atlix my signature in presence of two witnesses.
